Answer:

Data is stored on a hard disk drive as a result of magnetism. A file or data is represented in bits on a disk, with 1 representing a magnetized entity and 0 for an unmagnetized surface.

Explanation:

A hard disk drive (HDD) is an electro-magnetic tool for storing data in computing. It is made of moving parts like a platter and read/write head for reading and writing data to the disk.

To read or write data on a disk, the platter spins at a very high speed ( 5000 RPM to 10000 RPM), and the head, at the right surface, writes or reads a bit 1 as a magnetized surface and 0 as unmagnetized.

Translate each of these statements into logical expressions using predicates, quantifiers, and logical connectives. a) Something

yKpoI14uk [10]

Answer:

Let P(x) = x is in the correct place

Let Q(x) = x is in the excellent place

R(x) denotes the tool

Explanation:

a) Something is not in the correct place.

P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:

∃x¬P(x)

b) All tools are in the correct place and are in excellent condition.

R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:

∀ x ( R(x) → (P(x) ∧ Q(x))

c) Everything is in the correct place and in excellent condition.

Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧ means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:

∀ x (P(x) ∧ Q(x)
